    摘要: A photovoltaic module having a light transmissive front layer, a back layer, and a plurality of interconnected photovoltaic cells disposed between the light transmissive front layer and the back layer has a CTE-modified composite encapsulant is interposed between the plurality of solar cells and the light transmissive front layer. The composite encapsulant includes a bulk encapsulant transmissive to visible and near visible wavelengths of the solar spectrum and having a base coefficient of thermal (CTE) expansion, and an encapsulant CTE modifier in the bulk encapsulant. The encapsulant CTE modifier is substantially evenly distributed through the composite encapsulant thickness and interacts with the bulk encapsulant to reduce the effective CTE of the composite encapsulant below that of the bulk encapsulant.

    摘要: Provided herein are methods of polishing, cleaning and texturing back contacts of thin-film solar cells. According to various embodiments, the methods involve irradiating sites on the back contact with laser beams to remove contaminants and/or smooth the surface of the back contact. The back contact, e.g., a molybdenum, copper, or niobium thin-film, is smoothed prior to deposition of the absorber and other thin-films of the photovoltaic stack. In certain embodiments, laser polishing of the back contact is used to enhance the diffusion barrier characteristics of the back contact layer, with all or a surface layer of the back contact becoming essentially amorphous. In certain embodiments, the adhesion of the absorber layer is enhanced by the textured back contact and by the presence of the amorphous metal at the deposition surface.

    摘要: A method of manufacturing improved thin-film solar cells entirely by sputtering includes a high efficiency back contact/reflecting multi-layer containing at least one barrier layer consisting of a transition metal nitride. A copper indium gallium diselenide (Cu(InXGa1−X)Se2) absorber layer (X ranging from 1 to approximately 0.7) is co-sputtered from specially prepared electrically conductive targets using dual cylindrical rotary magnetron technology. The band gap of the absorber layer can be graded by varying the gallium content, and by replacing the gallium partially or totally with aluminum. Alternately the absorber layer is reactively sputtered from metal alloy targets in the presence of hydrogen selenide gas. RF sputtering is used to deposit a non-cadmium containing window layer of ZnS. The top transparent electrode is reactively sputtered aluminum doped ZnO. A unique modular vacuum roll-to-roll sputtering machine is described. The machine is adapted to incorporate dual cylindrical rotary magnetron technology to manufacture the improved solar cell material in a single pass.
